WILLIAM BANWARTH, OF GARY, SOUTH DAKOTA.

ACETYLENE-GAS GENERATOR.

Speccation of Letters Patent.

Patented Aug. 17, 1915.

Application filed September 29, 1914. Serial No. 864,090.

To all whom it may concern Be it known that I, VILLIAM BANwAn'rr-r, a citizen oi' the United States, residing at Gary, in the county of Deuel and State of South Dakota, have invented certain new and useful Improvements in Acetylene-Gas Generators, ott which the following is a specification.

The present invention relates to acetylene gas generators and particularly to that class of such generators which operate upon the principle of submerging separate independent charges of carbid in a confined body of water to generate the gas.

The primary object of the invention is to provide an apparatus of this general class which will be of very simple construction, yet etiicient, safe and reliable in operation, and which will overcome diiliculties that have been encountered in attempts heretofore made to produce successful apparatus operating upon this principle.

Another object of the invention is to pro` vide an apparatus which is especially adapted for use in garages and other stations or the purpose of charging small tanks with acetylene gas to lbe carried on automobiles.

Another object of the invention is to provide a portable acetylene gas generator which may be readily moved Jfrom place to place without disassembling.

Vith these and other objects in view the invention resides in an arrangement em` bodying the essential features of construction and cooperative relationship pointed out in the sub-joined claims and explained in the illustrative embodiment fully set forth in the following description and accompanying drawing; also in certain novel details of construction to be found in said illustrative embodiment as also pointed out in the claims.

In said drawing z-Figure 1 is a vertical central section of an acetylene gas generator embodying the invention, parts being shown in elevation; Fig. 2 is a view of the inner side of the cover plate with parts attached; Fig. 3 is a view of the carbid basket showing the same partly open in full lines and closed in dotted lines; Fig. 1 is a perspective view of the inner side of the cover plate showing in detail the manner of attaching and suspending the carbid basket.

Referring to the drawings in detail, 1 represents a cylindrical tank or generating chamber having a screw-threaded cap 2 and an integral base 3. The cap 2 is provided with a central opening el over which a cover plate 5 is adapted to be secured. The tank is supported by legs 6 and braced by a bar 7 which connects two or more of the legs, it being also securely fixed to the base 3.

8 represents a drain valve in the side of the tank positioned slightly above the base 3.

9 represents a collapsible basket for the carbid which is constructed substantially of two parts 10 and 10', the parts being held together by the hinge 11 connecting their bases. Each of the parts 10 and 10 are provided with bails 12 and 12.

To adapt the cover 5 to properly suspend the carbid basket within the generating chamber, the cover plate is provided on its inner side with a supporting arm 13 adapt ed to receive the bails 12 and 12, and in order that the basket thus supported may be readily released from the outside when the cover 5 is in place, the arm 13 is made in the :form of a wiper and carried by a shaft 14 mounted to rotate in the cover and having upon its outer end a controlling handle 15, and said supporting arm or wiper is made to coperate with a stripping pin 16 so that when the shaft is rotated by the handle, the bails 12 and 12 of the basket are engaged by the stripping pin and made to slide off the end of the arm 13 successively, whereby the basket is opened and the carbid released before the basket is deposited in the water. An additional pin 17 is provided to prevent escape of the bails 12 and 12 before the wiper arm is moved. Means are also provided to prevent the movement of the wiper arm in the wrong direction, as for instance, by having it engage one of the pins when it reaches the limit of its return movement. To this end it is provided with a shoulder 1S. The stop thus produced prevents the bails 12 and 12 from moving over to the radial portion of the wiper arm out of reach of the stripping pin. In placing the carbid basket in position, the supporting and wiper arm 13 is held beyond the stripping position until the bails are introduced between the pins 16 and 17, whereupon the arm is thrown back to its supporting position which passes through the bails and the basket is thereby attached and held securely in position while the cover is being adjusted over the opening 4 formed in the cap 2, and until it is desired to deposit the carbid and develop the charge of gas.

To supply the generator with Water, a suitable pump 19 is provided on the outside of the chamber 1 which has direct communication With a Water supply pipe 20. This pump may also be used to advantage in flushing the chamber 1 when the drain valve is opened to expel the lime or slack carbid. 21 represents a suitable Water gage and 22 represents a cooler and purifier connected to the chamber by means of the pipe 23.

24 represents a service pipe for the delivery of the generated gas and 25 represents a suitable pressure gage.

It Will be seen from the foregoing de` scription that an acetylene gas generator constructed in accordance with the present invention Will provide eflicient means for producinga quantity of acetylene gas without danger of overheating and exploding any generated gas that may be stored in the top of the generator.

I claim 1. An acetylene gas generator comprising a Water containing chamber, and means for releasably supporting a charge of carbid over the Water in the said chamber, coinprising a vertically divided basket having its respective parts provided With separate bails, a support receiving both of said bails and means for displacing said bails from said support, successively. y

2. An acetylene gas generator, comprising a Water tank, a cover therefor and means for releasably supporting a charge of carbid above the Water in said tank, comprising a vertically divided basket having its respective parts provided With bails, a supporting arm on the cover receiving both of said bails, a stripping pin on said cover cooperating With said arm to successively strip the bails therefrom, a shoulder provided on said arm and adapted to engage a pin on said cover for limiting the movement of the arm in the Wrong direction.

The foregoing specification signed at Gary, South Dakota7 this 8th day of September, 1914.
